The first rotation axis L1 and the second rotation axis L2 are orthogonal to each other, and the rotation detection sensor 140 and the tilt detection sensor 160 are used to rotate the magnet 120. And the operation of the tilting operation is detected independently. This magnetic detection device 100 is used, for example, in a configuration built in a lever combination switch 10 or the like for operating a winker of the vehicle 5 or the like. Therefore, in the present embodiment, the operation unit will be described as the operation lever 20 of the lever combination switch 10 shown above. In addition, the operation part should just be able to operate around the 1st and 2nd rotating shaft, and is not restricted to what is mounted in a vehicle.

(First embodiment)
(Whole structure of the magnetic detection apparatus 100)
FIG. 1 is an explanatory diagram showing the interior of a vehicle on which a magnetic detection device according to an embodiment of the present invention is mounted. FIG. 2 is a perspective view showing an appearance of a lever combination switch including a magnetic detection device. FIG. 3A is a plan view showing the magnetic detection device according to the first embodiment of the present invention viewed from the direction of the first rotation axis, and FIG. 3B is a magnetic view viewed from the direction of the second rotation axis. It is a front view which shows a detection apparatus. FIG. 4 is a block diagram showing the configuration of the magnetic detection device according to the embodiment of the present invention.

The lever combination switch 10 is an operation device capable of operating a turn signal (direction indicator) or a headlamp of the vehicle 5, for example. As shown in FIG. 1, the lever combination switch 10 is mounted in the vicinity of the steering 6 of the vehicle, and is disposed so as to protrude from a steering column cover 7 that covers the steering column.

As shown in FIG. 2, the lever combination switch 10 accommodates therein an operation lever 20 that performs a lever operation and a magnetic detection device 100 that detects an operation amount by a rotation operation and a tilt operation by the operation lever 20. The main unit 30 is configured. A lever combination switch 10 that protrudes to the right side in FIG. 1 operates, for example, a direction indicator and a headlamp. In the present embodiment, the configuration and operation of the magnetic detection device in which the operation lever 20 as the operation unit performs the rotation operation around the first rotation axis L1 and the tilting operation around the second rotation axis L2. Will be described.

As shown in FIG. 2, when the operation lever 20 is operated in the TL and TR directions, it is operated around the first rotation axis. The operation around the first rotation axis L1 is a rotation operation around the rotation axis L1 in the magnetic detection device 100 shown in FIG. 3A.

Further, as shown in FIG. 2, when the operation lever 20 is operated in the P and D directions, it is operated around the second rotation axis. The operation around the second rotation axis L2 is a tilting operation around the rotation axis L2 in the magnetic detection device 100 shown in FIG. 3B. The second rotation axis L2 is orthogonal to the first rotation axis L1.

As shown in FIGS. 2, 3A, and 3B, the magnetic detection device 100 is accommodated in the main body 30, and the magnet 120 is rotated around the first rotation axis L1 by the operation lever 20 that is an operation unit. Alternatively, the tilting operation is performed around the second rotation axis L2. The rotation around the first rotation axis L1 and the tilting around the second rotation axis L2 can operate independently. In addition, transmission of the driving force from the operation lever 20 to the magnet 120 can take a known mechanism and configuration such as a link mechanism, a gear mechanism, and a cam mechanism.

(Configuration of magnet 120)
As shown in FIGS. 3A and 3B, the magnet 120 is formed in a disk shape, for example, a permanent magnet such as an alnico magnet, a ferrite magnet, or a neodymium magnet, or a ferrite, neodymium, samakoba, or samarium iron nitrogen system. And a magnetic material such as polystyrene, polyethylene, polyamide, and a synthetic resin material such as acrylonitrile / butadiene / styrene (ABS) and mixed to form a desired shape.

As shown in FIGS. 3A and 3B, the magnet 120 is magnetized in a direction perpendicular to the first rotation axis L1 and perpendicular to the second rotation axis L2. Due to this magnetization, the tilt detection sensor 160 side of the magnet 120 becomes the N pole and the opposite side becomes the S pole. Magnetization with reverse polarity is also possible. With this magnetization, as will be described later, as shown in FIGS. 5A to 5C and 6A to 6C, a typical magnetic flux (magnetic field) is radiated from the N pole of the magnet 120 toward the S pole, and from the N pole to the radius. The magnetic flux 500 radiated toward the outer side in the direction passes through the upper and lower sides of the disk portion 121 of the magnet 120 to form a magnetic flux 500 that converges to the S pole.

(Configuration of control unit 130)
As shown in FIG. 4, the control unit 130, for example, a CPU (Central Processing Unit) that performs operations and processes on acquired data according to a stored program, a RAM (Random Access Memory) that is a semiconductor memory, and a ROM ( Read only memory) and the like. In this ROM, for example, a program for operating the control unit 130 is stored. The RAM is used as a storage area for temporarily storing calculation results, for example.

The control unit 130 rotates around the first rotation axis L1 and the second rotation axis L2 of the operation lever 20 based on the detection signal S1 output from the rotation detection sensor 140 and the detection signal S2 output from the tilt detection sensor 160. The four operation positions based on the rotation of can be determined.

For example, the control unit 130 can generate an operation signal S3 indicating the operation position of the operation lever 20 and output the operation signal S3 to the vehicle control unit of the vehicle 5.

(Configuration of magnetic detector)
The magnetic detection device 100 includes a rotation detection sensor 140 and a tilt detection sensor 160 as a magnetic detection unit. The rotation detection sensor 140 and the tilt detection sensor 160 are both MR (Magneto Resistive) sensors using magnetoresistive elements. As another magnetic sensor, a Hall sensor using a Hall element or the like can be used.

As shown in FIG. 3B, the rotation detection sensor 140 is disposed below the disc portion 121 of the magnet 120 on the first rotation axis L1. As shown in FIG. 3B, the rotation detection sensor 140 is positioned and fixed in a state where it is mounted on a substrate 190 that is separated from the lower surface 122 of the magnet 120 by a predetermined distance.

5A is a perspective view showing the magnetizing direction of the magnet, the state of magnetic flux, and the positional relationship of the rotation detection sensor, FIG. 5B is a cross-sectional view taken along the line EE of FIG. 5A, and FIG. It is a top view which shows the positional relationship of the state of magnetic flux and the rotation detection sensor 140 seen from the direction.

As shown in FIGS. 5A to 5C, the typical magnetic flux of the magnet 120 is radiated from the N pole of the magnet 120 toward the S pole, and the magnetic flux radiated from the N pole in the radial direction is the disk of the magnet 120. A magnetic flux 500 that converges on the south pole through the lower side of the part is formed. The rotation detection sensor 140 is arranged so as to detect only a change in the direction of the magnetic field of the magnetic flux 500.
That is, the rotation detection sensor 140 can detect a change in the direction of the magnetic field associated with the rotation operation of the magnet 120 around the first rotation axis L1 and is accompanied by a tilting operation of the magnet 120 around the second rotation axis L2. It is arranged at a position where the direction of the magnetic field does not change. The rotation detection sensor 140 is configured by a bridge of MR elements to be described later, and is arranged so that a surface on which the bridge is configured becomes a detection surface 141 for detecting a change in magnetic field direction.

As shown in FIG. 3B, the tilt detection sensor 160 is arranged at a position close to the outer periphery of the magnet 120 at the center of the thickness of the disc portion 121 at the neutral position of the magnet 120 (a position where the tilt operation is not performed). As shown in FIG. 3B, the tilt detection sensor 160 is mounted on a vertical board 191 erected on the board 190.

6A is a perspective view showing the magnetization direction of the magnet, the state of magnetic flux, and the positional relationship of the tilt detection sensor, FIG. 6B is a cross-sectional view taken along line EE of FIG. 6A, and FIG. It is a top view which shows the state of the magnetic flux seen from the direction, and the positional relationship of the tilt detection sensor 160. FIG.

As shown in FIGS. 6A to 6C, the typical magnetic flux of the magnet 120 forms a magnetic flux 500 radiated from the N pole to the S pole of the magnet 120 and is radiated radially outward from the N pole. The magnetic flux 501 is formed. The tilt detection sensor 160 is arranged so as to detect only a change in the direction of the magnetic field of the magnetic flux 501 on the N pole side. In other words, the tilt detection sensor 160 can detect a change in the direction of the magnetic field associated with the tilting operation of the magnet 120 and is disposed at a position where the direction of the magnetic field associated with the rotating operation of the magnet 120 does not change. The tilt detection sensor 160 is configured by a bridge of MR elements, which will be described later, and is arranged so that a surface on which the bridge is configured becomes a detection surface 161 for changing the direction of the magnetic field.

(Operation and detection operation of the magnetic detection device 100)
Below, operation | movement of the magnetic detection apparatus 100 is demonstrated, referring each figure. That is, the detection operation of the rotation detection sensor 140 based on the rotational movement of the magnet 120 when it is rotated around the first rotation axis L1, and the rotation of the magnet 120 when it is rotated around the second rotation axis L2. The detection operation of the tilt detection sensor 160 due to movement will be described.

When the operation lever 20 is rotated around the first rotation axis L1, the magnet 120 is rotated around the first rotation axis L1. As a result, the direction of the magnetic field of the magnetic flux 500 passing through the rotation detection sensor 140 shown in FIGS. 5A and 5C changes. This change in the direction of the magnetic field is a change on the detection surface 141 of the rotation detection sensor 140 shown in FIGS. 3B, 5A, and 5B, so that the change in the direction of the magnetic field can be detected by the rotation detection sensor 140. On the other hand, as shown in FIGS. 3B, 6A, and 6B, since the change is substantially perpendicular to the detection surface 161 of the tilt detection sensor 160, the tilt detection sensor 160 does not detect a change in the direction of the magnetic field due to the rotation operation.

When the operation lever 20 is tilted around the second rotation axis L2, the magnet 120 is tilted around the second rotation axis L2. As a result, the direction of the magnetic field of the magnetic flux 501 passing through the tilt detection sensor 160 shown in FIGS. 6A and 6C changes. Since the change in the direction of the magnetic field is a change on the detection surface 161 of the tilt detection sensor 160 shown in FIGS. 3B, 6A, and 6B, the change in the direction of the magnetic field can be detected by the tilt detection sensor 160. On the other hand, as shown in FIGS. 3B, 5A, and 5B, the rotation detection sensor 140 does not detect a change in the direction of the magnetic field due to the tilting operation because the change is substantially orthogonal to the detection surface 141 of the rotation detection sensor 140.

(Rotation detection operation)
FIG. 7A is a circuit diagram showing an example of a magnetic sensor, and FIG. 7B is a signal waveform diagram showing detection signals S1 and S2 detected by the first MR bridge and the second MR bridge.

FIG. 7A shows a configuration in which two full bridges are arranged with a rotation angle of 45 °. An intermediate voltage is input to the operational amplifier (differential amplifier) OP1 from the

nodes

215b and 215d of the first MR bridge 210 (

MR elements

211, 212, 213, and 214), and the detection signal S1 can be detected as a differential signal. ing. Similarly, intermediate voltages are input to the operational amplifier (differential amplifier) OP2 from the

nodes

225b and 225d of the second MR bridge 220 (

MR elements

221, 222, 223, and 224), and the detection signal S2 can be detected as a differential signal. It is configured. Note that the reference voltage Vcc is applied to the

nodes

215a and 225a, and the

nodes

215c and 225c are grounded (GND). Moreover, the detection signal S1 and the detection signal S1 are output to the vehicle control unit of the vehicle 5, for example.

The rotation detection sensor 140, which is a magnetic sensor configured as described above, outputs detection signals S1 and S2 as changes in the direction of the magnetic field of the magnet 120 disposed facing the rotation detection sensor 140, and is shown in FIG. 7B. Thus, it is possible to detect with a phase difference of 45 °. For example, by performing an Arctan process that takes the arc tangent by dividing the two detection signals S1 and S2, for example, the direction position of the magnetic field is calculated with reference to the Arctan table stored as a table in the storage unit. be able to. The calculated direction position of the magnetic field corresponds to the rotational operation position of the operation lever 20. Therefore, it is possible to detect what kind of rotation operation (for example, a left turn operation in the direction of arrow TL or a right turn operation in the direction of arrow TR) is performed around the first rotation axis L1.

Similarly, the tilt detection sensor 160, which is a magnetic sensor configured as described above, outputs detection signals S1 and S2 as a change in the direction of the magnetic field of the magnet 120 disposed opposite to the tilt detection sensor 160, As shown in FIG. 7B, detection can be performed with a phase difference of 45 °. For example, by performing an Arctan process that takes the arc tangent by dividing the two detection signals S1 and S2, for example, the direction position of the magnetic field is calculated with reference to the Arctan table stored as a table in the storage unit. be able to. The calculated direction position of the magnetic field corresponds to the tilting operation position of the operation lever 20. Therefore, it is possible to detect what kind of tilting operation (for example, a passing operation in the direction of arrow P or a dimmer operation in the direction of arrow D) is performed around the second rotation axis L2.

(Effects of the first embodiment)
The magnetic detection device according to the present embodiment has the following effects.
(1) In the present embodiment, a magnet 120 that is rotated around the first rotation axis L1 by the operation unit and is tilted around the second rotation axis L2, and the first of the magnet 120 A rotation detection sensor 140, which is a first magnetic detection unit that detects a change in the magnetic field around the rotation axis L1, and a second magnetic detection unit that detects a change in the magnetic field around the second rotation axis L2 of the magnet. A tilt detection sensor 160, and the first rotation axis L1 and the second rotation axis L2 are orthogonal to each other, and the rotation detection sensor 140 and the tilt detection sensor 160 are operations for rotating and tilting the magnet 120. Are detected independently. As a result, the movement in two directions can be independently and accurately detected with one magnet.
(2) The rotation detection sensor 140 is provided at a position that can detect a change in the direction of the magnetic field associated with the rotation operation of the magnet 120 and that does not change the direction of the magnetic field associated with the tilting operation of the magnet 120. That is, the rotation detection sensor 140 can detect a change in the direction of the magnetic field associated with the rotation operation of the magnet 120 around the first rotation axis L1 and is accompanied by a tilting operation of the magnet 120 around the second rotation axis L2. It is arranged at a position where the direction of the magnetic field does not change. The rotation detection sensor 140 is constituted by a bridge of the above-described MR element, and is arranged so that a surface on which the bridge is formed becomes a detection surface 141 for detecting a change in magnetic field direction. On the other hand, the tilt detection sensor 160 can detect a change in the direction of the magnetic field accompanying the tilting operation of the magnet 120, and is provided at a position where the direction of the magnetic field accompanying the rotating operation of the magnet 120 does not change. In other words, the tilt detection sensor 160 can detect a change in the direction of the magnetic field associated with the tilting operation of the magnet 120 and is disposed at a position where the direction of the magnetic field associated with the rotating operation of the magnet 120 does not change. The tilt detection sensor 160 is configured by the bridge of the MR element described above, and is arranged so that the surface on which the bridge is configured becomes the detection surface 161 of the direction change of the magnetic field. With such a configuration, the crosstalk of the detection signal due to the movement of one magnet in two directions is reduced, and the movement in two directions can be independently and accurately detected with one magnet.
(3) According to the arrangement configuration of the magnet 120, the rotation detection sensor 140, and the tilt detection sensor 160 as described above, a signal is output with the neutral position of the rotation operation or tilt operation as an initial position. The center of the level is constant, and stable detection operation is possible.
(4) A configuration in which two magnetometers are used to detect one magnet can reduce the cost compared to a conventional configuration in which two magnets are used. Further, by reducing the number of magnets, it is possible to reduce the size of the magnetic detection device.

(Second Embodiment)
FIG. 8A is a plan view showing the magnetic detection device according to the second embodiment of the present invention viewed from the direction of the first rotation axis, and FIG. 8B is a magnetic view viewed from the direction of the second rotation axis. It is a front view which shows a detection apparatus.

In the second embodiment, the magnet is formed in a spherical shape instead of the disk shape shown in the first embodiment. The other configuration is the same as that of the first embodiment, and a duplicate description is omitted.

(Configuration of magnet 125)
The magnet 125 is formed in a spherical shape as shown in FIGS. 8A and 8B, and is, for example, a permanent magnet such as an alnico magnet, a ferrite magnet, or a neodymium magnet, or a ferrite-based, neodymium-based, samakoba-based, samarium-iron-nitrogen-based, or the like. It is a plastic magnet formed by mixing a magnetic material and a synthetic resin material such as polystyrene, polyethylene, polyamide, acrylonitrile / butadiene / styrene (ABS), etc., into a desired shape.

As shown in FIGS. 8A and 8B, the magnet 125 is magnetized in a direction perpendicular to the first rotation axis L1 and perpendicular to the second rotation axis L2. Due to this magnetization, the tilt detection sensor 160 side of the magnet 125 becomes the N pole and the opposite side becomes the S pole. Magnetization with reverse polarity is also possible. Due to this magnetization, as in the first embodiment, as shown in FIGS. 5A to 5C and 6A to 6C, a typical magnetic flux (magnetic field) is radiated from the N pole of the magnet 125 toward the S pole. The magnetic flux radiated from the north pole in the radial direction passes through the outer peripheral portion 126 of the magnet 125 to form a magnetic flux that converges to the south pole.

(Effect of the second embodiment)
According to the second embodiment, in addition to the effects of the first embodiment, the following effects are obtained. That is, since the magnet 125 is formed in a spherical shape, the same magnetic circuit can be configured with respect to the first rotation axis L1 and the second rotation axis L2. Therefore, an ideal magnetic circuit is obtained, and the detection levels of the rotation detection sensor 140 and the tilt detection sensor 160 are the same, so that more stable and highly accurate detection is possible.

As mentioned above, although embodiment of this invention was described, these embodiment is only an example and does not limit the invention which concerns on a claim. These novel embodiments can be implemented in various other forms, and various omissions, replacements, changes, and the like can be made without departing from the scope of the present invention. In addition, not all the combinations of features described in these embodiments are essential to the means for solving the problems of the invention. Furthermore, these embodiments are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
